avcodec/hevcdec: Don't allocate redundant HEVCContexts

The HEVC decoder has both HEVCContext and HEVCLocalContext
structures. The latter is supposed to be the structure
containing the per-slicethread state.

Yet up until now that is not how it is handled in practice:
Each HEVCLocalContext has a unique HEVCContext allocated for it
and each of these coincides except in exactly one field: The
corresponding HEVCLocalContext. This makes it possible to pass
the HEVCContext everywhere where logically a HEVCLocalContext
should be used. And up until recently, this is how it has been done.

Yet the preceding patches changed this, making it possible
to avoid allocating redundant HEVCContexts.
